There are a lot of ways to host a Resolve project server, but each of them has their own set of issues. The official project server requires manual backups, and other options can be complicated for those that don't have access to an IT team. Hopefully this is a simpler solution for smaller teams!
- **Compatible with Resolve's existing backup/restore functions** - All backup files use the standard *.backup file syntax that Resolve uses, unlike many of the PostgreSQL backup solutions that exist now.
Many of these don't need to be edited, but here are the ones you might want to change:
| Environment Variable |Meaning|
|---|---|
| POSTGRES_DB | This is the name (or comma/space separated list of names) of the database from the previous step |
| POSTGRES_USER | This is the database username from the previous step |
| POSTGRES_PASSWORD | This is the database password from the previous step |
| SCHEDULE | This is a [cron string](https://www.freeformatter.com/cron-expression-generator-quartz.html) for how often backups are created. can be "@daily", "@every 1h", etc |
| BACKUP_KEEP_DAYS | Number of daily backups to keep before removal.
| BACKUP_KEEP_WEEKS | Number of weekly backups to keep before removal.
| BACKUP_KEEP_MONTHS | Number of daily backups to keep before removal.
| TZ | This is your timezone, here is [a list](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)|
5. Container Station will download the files it needs and start the app. Once it's done, you should be able to connect Resolve to the IP address of your QNAP using the database name and credentials
3. Move your modified docker-compose.yml file to a folder on your Linux machine, then navigate to that folder in the terminal.
4. Run:
```docker-compose up -d```
5. Docker-compose will download the files it needs and start the app. Once it's done, you should be able to connect Resolve to the IP address of your QNAP using the database name and credentials
Generally, Resolve is not very tolerant of mismatched PostgreSQL versions. The Windows version of Resolve installs 9.5.4, and the Mac version installs 9.5.19. Unfortunately the major release 9.5 is EOL, and 9.5.4 in particular has a lot of vulnerabilities that make it insecure. Since most people are still using the default Resolve credentials for their server, security generally isn't the biggest concern, but if you are trying to secure your project server, you will want to move to a supported version of PostgreSQL.
Resolve still uses a legacy feature that has been removed in PostgreSQL 12, so the latest major version that is useable is 11, which will be maintained until November 9, 2023.
1.**Uninstall PostgreSQL 9.5.4** - In your Windows application settings find PostgreSQL 9.5.4 and uninstall it.
2.**Download PostgreSQL 11** - Download the latest Windows version of PostgreSQL 11 from [the EDB Downloads Page](https://www.enterprisedb.com/downloads/postgres-postgresql-downloads) and install it.
3.**Link Resolve to the new version** - Open Resolve, and connect to/open a PostgreSQL database. Start to run a database command (optimize, backup, restore) and Resolve will ask you to point it to PostgreSQL bin folder. This is inside the folder you picked in the PostgreSQL 11 installation, likely "C:\Program Files\PostgreSQL\11\bin"
Unfortunately, Resolve on a Mac doesn't have a way to point to a different version of PostgreSQL. From my limited tests, it seems that you can still connect to a PostgreSQL 11 server from a Mac, you just won't be able to optimize, backup, or restore your database.
